Shadows of Disaster — Cathy Beveridge

In this fascinating historical novel, twelve-year-old Jolene travels back in time to the year 1903 and finds herself in the coal mining town of Frank on the eve of Canada's deadliest rockslide. Disguised as a boy, Jolene must face the wrath of an impatient teacher, challenge her ability as a gymnast, and disentangle herself from an embarrassing love triangle. She must also face the fact that the generous people of the town of Frank are living in the path of disaster and she cannot save them. She can, however, save herself and her grandfather and does so in a desperate race against time. But the lessons of the past are not lost in the present. Jolene discovers a way to revitalize her father's museum by preserving the story in history, and she prepares herself to take a few risks -- this time as a girl.
